Overview

On the park’s east side, the Barron River skims over water‑polished granite to form a natural waterslide and a string of clear pools. It’s equal parts playground and picnic rock—people slide, swim, sun on warm slabs, and then wander downstream to glimpse the actual High Falls (do not swim there).

Getting There

  • Shortest hike: Follow the High Falls Trail for about 4.5 km through mixed forest to the chutes. The trailhead sits roughly 13 km past Sand Lake Gate off Barron Canyon Road, down a short dirt spur to the parking lot.
  • Longer backpacking approach: From Achray, the Eastern Pines Backpacking Trail loops about 20 km with access to High Falls Bay on Stratton Lake.
  • Paddle-in option: Launch at Achray on Grand Lake, make a brief portage around a small dam into Stratton Lake, then paddle about 8.5 km (roughly two hours) to High Falls Bay and walk over to the slide.

Camping Options

If you want sunrise slides and empty pools, stay close: four waterfront backcountry sites sit a short walk from the waterslide. There are 20+ additional interior sites on Stratton and St. Andrews lakes—St. Andrews is the quieter bet. Frontcountry fans can base at nearby Achray Campground (45 sites plus a heated yurt, sandy beaches, and flush toilets). Backcountry fees are per person (about $12 adult, ~$6 under 18) with a max of nine people per site; reserve early.

Safety & Etiquette

Treat it like moving water. Scout the chute before sliding, supervise kids, and a PFD is a smart call. The brink of the actual High Falls is about 100 m downstream—look, don’t swim. Poison ivy is common along trails and shorelines. There are no services at the slide: pack out all trash, and handle bathroom needs at established facilities before you go.

What You’ll See

Beyond the slide, the Barron system is classic Canadian Shield—granite slabs, glacial erratics, and pine‑rimmed lakes. Around the pools you may spot frogs and small water snakes warming on the rocks.

Best Time to Visit

Summer weekends can feel like a beach day—go mid‑week or in the shoulder season for space to spread out. Aim for early morning or late afternoon for softer light, cooler rock, and fewer people. After heavy rain, some approach sections can be waterlogged; check park advisories before you head out.

Permits & Practicalities

Day‑use or camping permits are required; pick up day permits at Sand Lake Gate and reserve backcountry or campground stays through Ontario Parks. Bring sturdy water shoes for traction on slick granite, plenty of water, and a map if you’re hiking or paddling in. If you’re paddling, budget extra time for wind on Grand and Stratton.

Pros

  • Smooth granite waterslide with deep pools for swimming
  • Four backcountry campsites a short walk from the slide

Cons

  • Peak-summer crowds
  • Moving water; the current can be strong in places

Tips

  • Visit mid‑week or in shoulder season to dodge peak crowds.
  • Wear water shoes for grip on slick granite and to protect your feet.
  • Scout the chute and consider a PFD; stay well away from the brink 100 m downstream.
  • If paddling from Achray, expect a short dam portage and possible headwinds on Grand and Stratton.
  • Pick up day‑use permits at Sand Lake Gate and reserve nearby campsites early.
